Abstract
Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) can induce life-threatening complications, including acute kidney injury, encephalopathy, and gastrointestinal complications. On the other hand, there have been few reports of cholecystitis associated with STEC-HUS. In this study, we report the case of an 83-year-old Japanese man who developed recurrent acute cholecystitis associated with STEC-HUS. Prior to establishing a definite diagnosis of STEC-HUS, plasma exchange and hemodialysis were initiated, which resulted in a rapid increase in the platelet count and decrease in lactate dehydrogenase levels. The patient presented an enlarged gallbladder detected by computed tomography during the course of treatment. Due to recurrent flare-ups, the patient had to undergo several rounds of endoscopic retrograde biliary drainage and, ultimately, cholecystectomy to prevent relapse of acute cholecystitis. Since cholecystitis was thought to have been caused by complex mechanisms in this case, we discussed those from multiple perspectives. This case report highlights the need for particular care to be given to the management of pre-existing diseases as well as STEC-HUS, especially in older patients.

Abstract
Biliary sludge is an extremely viscous sediment, consisting essentially of calcium bilirubinate granules and cholesterol crystals, which, due to its high viscosity, has poor and slow movement, leading to a mass-like configuration called tumefactive biliary sludge. Tumefactive sludge was first described with the advent of ultrasonography in the 1970s and is an uncommon intraluminal lesion of the gallbladder (GB). The differential diagnoses for an echogenic mass in the GB lumen include GB carcinoma, tumefactive sludge, and gangrenous cholecystitis. Ultrasonography is the election method for the screening of GB diseases, with diagnostic accuracy exceeding 90%. The point-of-care ultrasound (POCUS) has shown a major improvement in the evaluation of hepatobiliary diseases. POCUS allows the detection of GB wall thickness, pericholestatic fluid, sonographic Murphy's sign, and dilatation of the common bile duct. The authors present a case of abdominal pain caused by the presence of tumefactive sludge in the GB, in which POCUS helped establish the diagnosis and therapeutic guidance.

Abstract
The significance of gallbladder sludge in cats remains largely unknown and has been speculated to be a pathologic finding in cats. The objectives of this retrospective, observational study were to determine the prevalence of gallbladder sludge in the population of cats presenting for abdominal ultrasound; to describe clinical signs, laboratory findings and certain abdominal ultrasound abnormalities; and to compare these findings to cats without gallbladder sludge. One hundred and ninety-two cats were included. Medical records were searched for cats with an abdominal ultrasound performed between October 2014-2015. Signalment, clinical signs, complete blood count, biochemical findings, presence or absence of gallbladder sludge, and hepatobiliary and pancreatic ultrasound findings were recorded. Gallbladder sludge was present in 44% of cats that underwent an abdominal ultrasound. There was no significant difference in age, sex, presenting clinical signs or clinicopathologic variables between the two groups. Gallbladder wall thickening significantly increased the odds of detecting gallbladder sludge (OR-3.7 95% CI 1.4 - 10.0). Gallbladder sludge was not associated with other ultrasonographic abnormalities of the liver, gallbladder, bile duct or pancreas. Gallbladder sludge is common in cats undergoing abdominal ultrasound and appears to be a non-specific finding. The clinical significance of concurrent gallbladder sludge and gallbladder wall thickening present on ultrasound in cats remains to be determined.

Abstract
Pregnancy is one of the risk factors for biliary sludge (BS) formation. In this cross-sectional study, a total of 959 pregnant women were included. Serum aspartate aminotransferase, alanine aminotransferase, sodium, potassium, triglycerides, cholesterol levels and the presence of ketones in urine were determined. The presence of BS was investigated using maternal abdominal ultrasound. The incidence of BS in pregnancies complicated by hyperemesis gravidarum (HG) was 14%. The degree of ketonuria and low birth weight were statistically higher in pregnancies with maternal BS than women without sludge. Total weight gain during pregnancies with BS was statistically lower than controls. The incidence of BS in pregnancies with HG does not appear to increase due to HG-related complications, such as dehydration, starvation and weight loss. However, the severity of HG may be worse when HG is associated with sludge.Impact StatementWhat is already known on this subject? The incidence of biliary sludge (BS) in pregnant women ranges between 10.9% and 36%. Some clinical conditions, such as pregnancy, prolonged fasting, total parenteral nutrition, rapid weight loss and ceftriaxone treatment can play a role in the formation of gallbladder sludge.What do the results of this study add? This is the first study to investigate the incidence of BS in hyperemesis gravidarum (HG) pregnancies. Results show that HG may transiently be associated with BS. HG is more likely to cause a transient increase in new sludge formation. The symptoms and complications related to HG may be more severe when HG is associated with BS.What are the implications of these findings for clinical practice and/or further research? Our study showed that BS can be found in HG patients, and HG can be a predisposing factor for new sludge formation, although this association is generally driven by advanced maternal age and increased baseline serum lipid and alanine aminotransferase levels. BS may also be independently associated with an increased risk of subsequent preterm delivery in women with HG.

Abstract
Background and study aims Endoscopic ultrasonography (EUS) is a tool widely used to diagnose bile duct lithiasis. In approximately one out of five patients with positive findings at EUS, sludge is detected in the bile duct instead of stones. The objective of this study was to establish the agreement among endosonographers regarding: 1. presence of common bile duct (CBD) stones, microlithiasis and sludge; and 2. the need for subsequent treatment. Patients and methods 30 EUS videos of patients with an intermediate probability of CBD stones were evaluated by 41 endosonographers. Experience in EUS and endoscopic retrograde cholangiopancreatography, and the endosonographers' type of practices were recorded. Fleiss' kappa statistics were used to quantify the agreement. Associations between levels of experience and both EUS ratings and treatment decisions were investigated using mixed effects models. Results A total of 1230 ratings and treatment decisions were evaluated. The overall agreement on EUS findings was fair (Fleiss' κ 0.32). The agreement on presence of stones was moderate (κ 0.46). For microlithiasis it was fair (κ 0.25) and for sludge it was slight (κ 0.16). In cases with CBD stones there was an almost perfect agreement for the decision to subsequently perform an ERC + ES. In case of presumed microlithiasis or sludge an ERC was opted for in 78 % and 51 % of cases, respectively. Differences in experience and types of practice appear unrelated to the agreement on both EUS findings and the decision for subsequent treatment. Conclusions There is only slight agreement among endosonographers regarding the presence of bile duct sludge. Regarding the need for subsequent treatment of bile duct sludge there is no consensus.

Ultrasound J 2020; 12:51. [PMID: 33270182 PMCID: PMC7714802 DOI: 10.1186/s13089-020-00199-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Accepted: 11/27/2020] [Indexed: 12/23/2022] Open
Abstract
Background The presence of intra-abdominal calcification in the pediatric population can be due to a wide range of conditions. Calcification in the abdomen can be seen in normal or abnormal anatomical structures. In some patients, abnormal calcification points towards the pathology; whereas in others, calcification itself is the pathology. After a thorough history and clinical examination, point-of-care ultrasound (POCUS) would complement the assessment of acute abdominal pain, based on the list of differentials generated as per the abdominal region. The main objective of this article is to review commonly encountered causes of intra-abdominal calcifications in the pediatric population and help in clinical decision-making in a Pediatric Emergency Department. Case presentation We describe a series of pediatric patients who presented to the Pediatric Emergency Department with acute abdominal pain, in whom point-of-care ultrasound helped expedite the diagnosis by identifying varying types of calcification and associated sonological findings. For children who present to the Pediatric Emergency Department with significant abdominal pain, a rapid distinction between emergencies and non-emergencies is vital to decrease morbidity and mortality. Conclusions In a child presenting to the Pediatric Emergency Department with abdominal pain, POCUS and the findings of calcifications can narrow or expand the differential diagnosis when integrated with history and physical exam, to a specific anatomic structure. Integrating these findings with additional sonological findings of an underlying pathology might raise sufficient concerns in the emergency physicians to warrant further investigations for the patient in the form of a formal radiological ultrasound and assist in the patient's early disposition. The use of POCUS might also help to categorize the type of calcification to one of the four main categories of intra-abdominal calcifications, namely concretions, conduit wall calcification, cyst wall calcification, and solid mass-type calcification. POCUS used thoughtfully can give a diagnosis and expand differential diagnosis, reduce cognitive bias, and reduce physician mental load. By integrating the use of POCUS with the history and clinical findings, it will be possible to expedite the management in children who present to the Pediatric Emergency Department with acute abdominal pain.

Abstract
Geriatric patients tend to have subtle presentations of biliary disorders and, if untreated, can decompensate acutely. Each biliary disorder warrants formulation of an individualized treatment plan with a multidisciplinary approach. Acute cholecystitis, a common complication of gallstones, is initially managed by conservative measures and subsequently, among patients with optimal surgical risk, through laparoscopic or open cholecystectomy. High-risk patients undergo temporization, percutaneous or endoscopic, followed by definitive intervention. Acute cholecystitis with complications (ie, perforation, gangrene, or small bowel obstruction) warrants emergent cholecystectomy. Gallstone migration into the biliary system can cause choledocholithiasis, often complicated by biliary pancreatitis or cholangitis if not intervened. Therapy for choledocholithiasis is based on biliary clearance through endoscopic and, infrequently, surgical approaches.

Abstract
CASE We present a case report of an 18-year-old woman who presented to a general surgeon with a several month history of intermittent right upper quadrant pain, strongly suggestive of symptomatic cholelithiasis and underwent a laparoscopic cholecystectomy. She was eventually found to have an osteoid osteoma (OO) of the right eighth rib. She was treated with radiofrequency ablation with complete resolution of symptoms 1 month after treatment. CONCLUSIONS In cases where a patient's age and risk factors would make the diagnosis of cholelithiasis less likely, OO should be added to the differential diagnosis of symptomatic right upper quadrant pain.

Abstract
Aim of the study This study aimed to evaluate the prevalence of gallbladder disease in gravid Nigerian women and to elucidate any association with gravidity and ABO blood group. Materials and Methods This was a descriptive cross-sectional study of six hundred and fifty-six (656) pregnant women recruited from March 2015 to March 2016. Hemoglobin genotype and blood group were recorded and a sonographic examination was performed using Siemens ultrasound scanner. Statistical analysis was done using STATA software for Windows. Results Age had a significant association with the occurrence of gallbladder diseases (Likelihood ratio = 7.116, P = 0.03). Two (0.3%) pregnant women had biliary sludge, 11 (1.7%) had gallstones while 643 (98%) had normal gallbladders. Also, only one (9.1%) primigravida woman with gallstone was found in this study while 10 (90.9%) of the women with gallstones were multigravida. All the pregnant women who had gallstone(s) had blood group O. Of the two women with biliary sludge; one had blood group A while the other had blood group O. Conclusions The incidence of gallbladder disease increased with age in this study. There was a higher prevalence of gallstones than sludge in pregnancy. Also, the incidence of gallstones increased with the number of pregnancies among the women with gallstones. Attention should be paid to the gallbladder during abdominal sonography in pregnancy.

Abstract
PRACTICAL RELEVANCE Abdominal ultrasound plays a vital role in the diagnostic work-up of many cats presenting to general and specialist practitioners. The biliary tree encompasses the liver, gall bladder and bile ducts, although only diseases affecting the latter two are discussed here. Diseases of the bile ducts and gall bladder are more common than those of the liver parenchyma and ultrasound plays an important role in their diagnosis. CLINICAL CHALLENGES Despite ultrasonography being a commonly used modality, many practitioners are not comfortable performing an ultrasound examination or interpreting the resulting images. Even differentiating between normal variation and pathological changes can be challenging for all but the most experienced. In addition, a lack of pathological change does not necessarily rule out disease; for example, absence of gall bladder and/or extrahepatic biliary distension is not sufficient to exclude the possibility of biliary obstruction, and in many cases of cholangitis the liver and biliary tree are unremarkable on ultrasound examination. EQUIPMENT Ultrasound facilities are readily available to most practitioners, although use of ultrasonography as a diagnostic tool is highly dependent on operator experience. AIM This review, part of an occasional series on feline abdominal ultrasonography, discusses the appearance of the normal and diseased biliary system. It is aimed at general practitioners who wish to improve their knowledge and confidence in feline abdominal ultrasound and is accompanied by high-resolution images. Percutaneous ultrasound-guided cholecystocentesis is also covered. Ultrasound examination of the liver was discussed in an article published in January 2019 and an upcoming article will cover hepatic vascular anomalies. EVIDENCE BASE Information provided in this article is drawn from the published literature and the author's own clinical experience.

Abstract
AIM To investigate whether gallbladder polypoid lesions (GPL) are accurately reported and managed by radiologists, sonographers, general practitioners (GPs) and surgeons. MATERIALS AND METHODS Consecutive abdominal ultrasound examinations indicating GPL in symptomatic patients performed during 2011-2013 were captured and analysed. The study comprised 244 patients who satisfied the inclusion criteria. RESULTS Of the ultrasound reports retrieved, 238/244 reports (98%) erroneously described the polypoid lesions as polyps. One hundred and thirty-two of the 244 (54%) reports recommended follow-up, 5/244 (2%) recommended no follow-up, 35/244 (14%) deemed the findings insignificant, and 72/244 (30%) did not comment. Regarding GP referral, 57/184 (31%) patients were correctly referred to general surgeons, 20/184 (11%) to gastroenterologists, and 107/184 (58%) were not referred to secondary care. Forty-three of the 244 patients (18%) underwent cholecystectomy. Regarding subsequent biliary presentations, 63/244 patients (26%) presented at a later date with biliary symptoms; 13/63 (21%) of these eventually had cholecystectomies with 2/13 (15%) experiencing potentially life-threatening pancreatitis episodes. Regarding the surgical approach, differences were observed in the way individual surgeons managed polypoid lesions, with some veering towards cholecystectomy, others towards follow-up ultrasound, and some towards discharge. CONCLUSION GPL tend to be misreported by radiologists and sonographers, unappreciated by GPs, and variably managed by surgeons. These factors delay definitive therapy and seem to contribute to future biliary presentations. A fresh educational approach is required to raise awareness among radiologists, sonographers, and GPs regarding the clinical relevance and possible representations of GPL, and a uniform strategy is needed for managing GPL.

Abstract
OBJECTIVE To investigate the association between three diet-quality scores corresponding to adherence to healthy dietary patterns [alternate Mediterranean (aMed), Alternate Healthy Eating Index (AHEI-2010), Dietary Approaches to Stop Hypertension (DASH)] and the risk of symptomatic gallstone disease. METHODS The study comprised 43 635 men of the Health Professionals Follow-up Study-an ongoing prospective cohort study of US health professionals. Participants were free of symptomatic gallstone disease and diabetes and provided dietary information every 4 years from 1986 (baseline) until 2012. The aMed, AHEI-2010 and DASH scores were generated and associated with the risk of symptomatic gallstone disease using Cox proportional hazards regression. RESULTS During 716 904 person-years of follow-up, 2382 incident cases of symptomatic gallstone disease were identified. All three scores were inversely associated with risk of symptomatic gallstone disease after adjustment for potential confounders including age, smoking, physical activity, energy and coffee intake [hazard ratios (HRs) and 95% confidence intervals (CIs)] comparing the highest with the lowest quintiles: aMed: 0.66 (0.57-0.77), AHEI-2010: 0.64 (0.56-0.74) and DASH: 0.66 (0.58-0.76)]. Findings were similar after additional adjustment for body mass index and after inclusion of asymptomatic cases. Associations were stronger when analysis was restricted to cases who had undergone cholecystectomy. CONCLUSIONS In this prospective cohort of male US health professionals, higher adherence to the aMed, AHEI-2010 and DASH diets was associated with lower risk of symptomatic gallstone disease. Dietary recommendations focusing on high-quality diets targeting symptomatic gallstone disease may lower the incidence of this prevalent disease.

Abstract
The terms biliary sludge and cholesterol microlithiasis (hereafter referred to as microlithiasis) were originated from different diagnostic techniques and may represent different stages of cholesterol gallstone disease. Although the pathogenesis of biliary sludge and microlithiasis may be similar, microlithiasis could be preceded by biliary sludge, followed by persistent precipitation and aggregation of solid cholesterol crystals, and eventually, gallstone formation. Many clinical conditions are clearly associated with the formation of biliary sludge and microlithiasis, including total parenteral nutrition, rapid weight loss, pregnancy, organ transplantation, administration of certain medications, and a variety of acute and chronic illnesses. Numerous studies have demonstrated complete resolution of biliary sludge in approximately 40% of patients, a cyclic pattern of disappearing and reappearing in about 40%, and progression to gallstones in nearly 20%. Although only a minority of patients with ultrasonographic demonstration of biliary sludge develop gallstones, it is still a matter of controversy whether microlithiasis could eventually evolve to cholesterol gallstones. Biliary sludge and microlithiasis are asymptomatic in the vast majority of patients; however, they can cause biliary colic, acute cholecystitis, and acute pancreatitis. Biliary sludge and microlithiasis are most often diagnosed ultrasonographically and bile microscopy is considered the gold standard for their diagnosis. Specific measures to prevent the development of biliary sludge are not practical or cost-effective in the general population. Laparoscopic cholecystectomy offers the most definitive therapy on biliary sludge. Endoscopic sphincterotomy or surgical intervention is effective for microlithiasis-induced pancreatitis. Ursodeoxycholic acid can effectively prevent the recurrence of solid cholesterol crystals and significantly reduce the risk of recurrent pancreatitis.

Abstract
Despite the overwhelming prevalence of cholelithiasis, many health care professionals are not familiar with the basic pathophysiology of gallstone formation. This article provides an overview of the biochemical pathways related to bile, with a focus on the physical chemistry of bile. We describe the important factors in bile synthesis and secretion that affect the composition of bile and consequently its liquid state. Within this biochemical background lies the foundation for understanding the clinical and sonographic manifestation of cholelithiasis, including the pathophysiology of cholesterol crystallization, gallbladder sludge, and gallstones. There is a brief discussion of the clinical manifestations of inflammatory and obstructive cholestasis and the impact on bile metabolism and subsequently on liver function tests. Despite being the key modality in diagnosing cholelithiasis, ultrasound has a limited role in the characterization of stone composition.

Safety of Eluxadoline in Patients with Irritable Bowel Syndrome with Diarrhea. Am J Gastroenterol 2017; 112:365-374. [PMID: 27922029 PMCID: PMC5318664 DOI: 10.1038/ajg.2016.542] [Citation(s) in RCA: 61] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2016] [Accepted: 10/01/2016] [Indexed: 02/06/2023]
Abstract
OBJECTIVES Eluxadoline is a mixed μ-opioid receptor (OR) and κ-OR agonist and δ-OR antagonist, approved for the treatment of irritable bowel syndrome with diarrhea (IBS-D). This analysis evaluated the safety and tolerability of eluxadoline 75 and 100 mg twice daily (BID) in one Phase 2 (IBS-2001) and two Phase 3 (IBS-3001 and IBS-3002) studies. METHODS Adults with IBS-D (Rome III criteria) were randomized to placebo or eluxadoline (75 or 100 mg) BID for 12 (IBS-2001), 26 (IBS-3002), or 52 (IBS-3001) weeks. Safety data were pooled. Adverse events (AEs) were assessed, with special focus on opioid-related AEs, including suspected sphincter of Oddi spasm (SOS) events. RESULTS 2,776 patients were included in the enrolled set; the safety set comprised 2,814 patients, based on actual treatments received. The most frequent AEs in the placebo and eluxadoline 75 and 100 mg groups were constipation (2.5, 7.4, and 8.1%, respectively) and nausea (5.0, 8.1, and 7.1%, respectively); discontinuation due to constipation was uncommon (0.3, 1.1, and 1.5%, respectively). Ten SOS events (10/1,839; 0.5%) occurred in eluxadoline-treated patients, manifesting as acute abdominal pain with elevated aminotransferases or lipase, or pancreatitis; all occurred in patients without a gallbladder. Eight of these events occurred with the higher dose of eluxadoline, within 1 week of initiation of therapy, and all resolved with eluxadoline discontinuation. There were five events independently adjudicated as pancreatitis not associated with SOS, three of which were associated with heavy alcohol use. CONCLUSIONS Eluxadoline was well tolerated in Phase 2 and 3 trials, with constipation and nausea the most common AEs. Consistent with the known adverse effects of opioid agonists, clinically apparent SOS events were observed in eluxadoline-treated patients. All occurred in patients without a gallbladder and the majority were observed in patients on the higher dose of eluxadoline, suggesting a possible association.

Abstract
BACKGROUND AND STUDY AIM Endoscopic ultrasonography (EUS) is an established diagnostic modality for diagnosing common bile duct (CBD) stones. Its use has led to a reduction in the number of endoscopic retrograde cholangiopancreatography (ERCP) procedures performed for suspected choledocholithiasis. We aimed to explore the role of EUS in detecting CBD stones and/or sludge in common gastroenterology practice. PATIENTS AND METHODS We reviewed case records of 268 consecutive patients who underwent (EUS) procedures performed to confirm or rule out the presence of CBD stones and/or sludge between November 2006 and January 2011 in the Reinier de Graaf Hospital, Delft, The Netherlands, which is a nonacademic community hospital. RESULTS On the basis of EUS findings, 169 of 268 (63%) patients did not undergo ERCP and were therefore not exposed to its risk of complications. Patients with positive findings on EUS (n=99) all underwent ERCP and endoscopic sphincterotomy. Only 57 of 99 (58%) had positive findings at ERCP. The main contributing factors to this finding seem to be time interval between EUS and ERCP and the type of CBD content (i.e. sludge, one CBD stone or more than one CBD stone) described. CONCLUSION In our common gastroenterology practice, EUS plays an important role in selecting patients suspected to have CBD stones or sludge for ERCP. Much is to be learned about the probability of spontaneous passage of CBD stones and sludge into the duodenum.

Abstract
With its excellent contrast and spatial resolution, and the ability to image in real-time, ultrasound is the main imaging modality for assessing the gallbladder (GB). The application of contrast-enhanced ultrasound (CEUS) of the GB is now increasingly recognized as a useful addition to ultrasound and other cross-sectional imaging in the assessment of neoplastic and non-neoplastic GB disease. With the ability to image microcirculation and optimal contrast resolution, CEUS allows high-quality delineation in real-time, allowing for increased diagnostic confidence. In addition, ultrasound contrast agents have a favorable safety profile and can be used if CT or MR contrast agents are contraindicated or undesired. In this review, the CEUS appearances of a range of GB diseases encountered are presented, including adenomyomatosis, polyps, carcinoma, sludge, and cholecystitis with mural ulceration or perforation.

Abstract
OBJECTIVES Gallbladder sludge is a common diagnosis on routine abdominal sonography, yet its clinical importance is uncertain, especially in outpatients. To determine its natural history and potential future complications in this setting, we reviewed the imaging and clinical histories of nonhospitalized patients with a diagnosis of sludge on sonography. METHODS We conducted a retrospective search of our institutional radiology information system for all sonographic reports using the key words "biliary sludge without gallstones" over a 3-year period. For each of the 104 patients with isolated biliary sludge on initial sonography, we reviewed the electronic medical records and all imaging for the development of pancreaticobiliary complications. RESULTS We found an overall prevalence of biliary sludge in outpatients of 1.8%. Of the 104 patients reviewed with a mean follow up of 630 days (21 months), 25 developed a pancreaticobiliary complication, including cholelithiasis, cholecystitis, choledocholithiasis, and pancreatitis. The most frequent complication was cholecystitis, with a total of 14 diagnoses (12 chronic acalculous and 2 acute with gallstones). An additional 6 patients developed gallstones without cholecystitis features; 4 patients developed pancreatitis; and 1 developed choledocholithiasis. Biliary sludge remained quiescent or resolved in 76% of patients. CONCLUSIONS Biliary sludge always represents a pathologic process, but its clinical implications among outpatients have not been previously investigated. Our ambulatory population developed pancreaticobiliary complications at similar rates as prior mixed-patient setting studies. Regardless of the patient setting, biliary sludge is likely of more clinical importance than previously regarded.

Abstract
Epidemiological and clinical studies have found that gallstone prevalence is twice as high in women as in men at all ages in every population studied. Hormonal changes occurring during pregnancy put women at higher risk. The incidence rates of biliary sludge (a precursor to gallstones) and gallstones are up to 30 and 12%, respectively, during pregnancy and postpartum, and 1-3% of pregnant women undergo cholecystectomy due to clinical symptoms or complications within the first year postpartum. Increased estrogen levels during pregnancy induce significant metabolic changes in the hepatobiliary system, including the formation of cholesterol-supersaturated bile and sluggish gallbladder motility, two factors enhancing cholelithogenesis. The therapeutic approaches are conservative during pregnancy because of the controversial frequency of biliary disorders. In the majority of pregnant women, biliary sludge and gallstones tend to dissolve spontaneously after parturition. In some situations, however, the conditions persist and require costly therapeutic interventions. When necessary, invasive procedures such as laparoscopic cholecystectomy are relatively well tolerated, preferably during the second trimester of pregnancy or postpartum. Although laparoscopic operation is recommended for its safety, the use of drugs such as ursodeoxycholic acid (UDCA) and the novel lipid-lowering compound, ezetimibe would also be considered. In this paper, we systematically review the incidence and natural history of pregnancy-related biliary sludge and gallstone formation and carefully discuss the molecular mechanisms underlying the lithogenic effect of estrogen on gallstone formation during pregnancy. We also summarize recent progress in the necessary strategies recommended for the prevention and the treatment of gallstones in pregnant women.

Abstract
UNLABELLED Cholestatic liver dysfunction (CLD) and biliary sludge often occur during critical illness and are allegedly aggravated by parenteral nutrition (PN). Delaying initiation of PN beyond day 7 in the intensive care unit (ICU) (late PN) accelerated recovery as compared with early initiation of PN (early PN). However, the impact of nutritional strategy on biliary sludge and CLD has not been fully characterized. This was a preplanned subanalysis of a large randomized controlled trial of early PN versus late PN (n = 4,640). In all patients plasma bilirubin (daily) and liver enzymes (alanine aminotransferase [ALT], aspartate aminotransferase [AST], gamma-glutamyl transpeptidase [GGT], alkaline phosphatase [ALP], twice weekly; n = 3,216) were quantified. In a random predefined subset of patients, plasma bile acids (BAs) were also quantified at baseline and on days 3, 5, and last ICU-day (n = 280). Biliary sludge was ultrasonographically evaluated on ICU-day 5 (n = 776). From day 1 after randomization until the end of the 7-day intervention window, bilirubin was higher in the late PN than in the early PN group (P < 0.001). In the late PN group, as soon as PN was started on day 8 bilirubin fell and the two groups became comparable. Maximum levels of GGT, ALP, and ALT were lower in the late PN group (P < 0.01). Glycine/taurine-conjugated primary BAs increased over time in ICU (P < 0.01), similarly for the two groups. Fewer patients in the late PN than in the early PN group developed biliary sludge on day 5 (37% versus 45%; P = 0.04). CONCLUSION Tolerating substantial caloric deficit by withholding PN until day 8 of critical illness increased plasma bilirubin but reduced the occurrence of biliary sludge and lowered GGT, ALP, and ALT. These results suggest that hyperbilirubinemia during critical illness does not necessarily reflect cholestasis and instead may be an adaptive response that is suppressed by early PN.

Abstract
AIM: To explore the relationship between Clonorchis sinensis (C. sinensis) infection and gallstone formation by observing the morphology and survival status of C. sinensis eggs in gallbladder bile, biliary sludge and gallstones from gallstone patients with C. sinensis infection.
METHODS: Twenty gallstone patients with C. sinensis infection were enrolled in this study. Their gallbladder bile, biliary sludge and gallbladder stones were collected to observe the morphology of C. sinensis eggs using optical microscopy and scanning electron microscopy (SEM). Von Kossa staining and X-ray energy dispersive spectroscopy were used to analyze the calcium content on the surface of eggs and the substance surrounding them. Trypan blue staining was used for evaluating the survival rate of eggs.
RESULTS: In gallbladder bile, 88.3% of C. sinensis eggs had typical morphology, while 56.7% of eggs in biliary sludge and 91.5% in stones were deformed (including changes in shape and size, egg cover loss, invisible internal miracidia and adhesion bilirubin on the surface or in their surroundings). Under SEM, egg shell showed an uneven texture shape, and its surface and surroundings were adhered with mucus-like substances in varying degrees. The calcium content of egg surface and surroundings gradually increased from the bile, biliary sludge to stones. The survival rates of eggs in bile, biliary sludge and stones were 86.6%, 42.1% and 11.5%, respectively.
CONCLUSION: In patients infected with C. sinensis, C. sinensis eggs can remain in the gallbladder by their uneven texture-like egg shell and mucus-like substance from the biliary tract. Eggs can be further deformed, degenerated, and even calcified to nucleation, resulting in the formation of biliary sludge and participating in gallstone formation.

Abstract
Single-dose pharmacokinetic (PK) profiles and multiple-dose PK modeling were compared for long-acting octreotide (20 or 60 mg) and prolonged-release lanreotide (90 or 120 mg) over 91 days; steady-state profiles were simulated. All treatments were well tolerated. Octreotide 20-mg profile showed increased concentration on day 1, lag from days 2 to 6, then prolonged plateau phase (days 11-41); 60-mg PK was dose proportional. Lanreotide 90-mg profile showed C(max) on day 1 then elimination (apparent t1/2 25.5 days); 120-mg profile was underproportional. Steady-state PK of octreotide 20 mg/28 d suggested a C(mean) of 1216 rhog/mL (range, 1065-1585) with low fluctuation index (43%). Steady-state PK of lanreotide 90 mg/28 d suggested a C(mean) of 4455 rhog/mL (range, 2499-9279) with high fluctuation index (152%). Long-acting octreotide had more predictable PK than prolonged-release lanreotide. Simulated steady-state profiles suggest long-acting octreotide could be optimized to meet individual patient needs. In contrast, prolonged-release lanreotide requires exposure constantly above the therapeutic target to enable monthly long-term therapy.

Abstract
Diseases of the gallbladder are common and costly. The best epidemiological screening method to accurately determine point prevalence of gallstone disease is ultrasonography. Many risk factors for cholesterol gallstone formation are not modifiable such as ethnic background, increasing age, female gender and family history or genetics. Conversely, the modifiable risks for cholesterol gallstones are obesity, rapid weight loss and a sedentary lifestyle. The rising epidemic of obesity and the metabolic syndrome predicts an escalation of cholesterol gallstone frequency. Risk factors for biliary sludge include pregnancy, drugs like ceftiaxone, octreotide and thiazide diuretics, and total parenteral nutrition or fasting. Diseases like cirrhosis, chronic hemolysis and ileal Crohn's disease are risk factors for black pigment stones. Gallstone disease in childhood, once considered rare, has become increasingly recognized with similar risk factors as those in adults, particularly obesity. Gallbladder cancer is uncommon in developed countries. In the U.S., it accounts for only ~ 5,000 cases per year. Elsewhere, high incidence rates occur in North and South American Indians. Other than ethnicity and female gender, additional risk factors for gallbladder cancer include cholelithiasis, advancing age, chronic inflammatory conditions affecting the gallbladder, congenital biliary abnormalities, and diagnostic confusion over gallbladder polyps.

Abstract
Endoscopically obtained bile aspirate was found to be an effective technique to identify patients with symptomatic gallbladder disease and negative diagnostic studies. Objectives: The experience of a single surgeon in a rural hospital over a 10-year period was analyzed with respect to the utilization of endoscopically obtained bile aspirates as an adjunct in the diagnosis of symptomatic gallbladder disease. Methods: A retrospective study of the author's entire cholecystectomy experience over a 10-year period with 641 patients was conducted to evaluate the utility of the bile aspirate in the preoperative selection of operative candidates and with respect to the ultimate pathologic diagnostic accuracy of the test. Results: Derivation of preoperative diagnosis via traditional standard means was possible in 479 patients. An endoscopically obtained positive bile aspirate was found in 162 additional patients who failed to have positive traditional diagnostic studies (acalculous gallbladder disease). Micro-pathology was determined to be present in 603 patients (94.07%). In 27 of the 38 negatives, there had been positive radiological studies (71%). In 11 of the 38, a positive preoperative bile aspirate had been obtained (28.9%). Of the 162 patients with a positive bile aspirate, 151 (93.21%) of the gallbladder specimens had confirmatory histologic analysis (92.1% confidence interval ± 3.95%). Conclusion: In patients with symptoms suggestive of clinical gallbladder disease and negative traditional diagnostic studies, the endoscopically obtained bile aspirate has been shown to be a highly reliable tool in establishing the diagnosis and is recommended as an aid in the appropriate selection of candidates who may benefit from cholecystectomy.

Abstract
Technologic advancements have allowed imaging modalities to become more useful in the diagnosis of hepatobiliary and pancreatic disorders. Computed tomography scanners now use multidetector row technology with contrast-delayed imaging for quicker and more accurate imaging. Magnetic resonance imaging with cholangiopancreatography can more clearly delineate liver lesions and the biliary and pancreatic ducts, and can diagnose pathologic conditions early in their course. Newer technologies, such as single-operator cholangioscopy and endoscopic ultrasonography, have sometimes shown superiority to traditional modalities. This article addresses the literature regarding available imaging techniques in the diagnosis and treatment of common surgical hepatobiliary and pancreatic diseases.

Abstract
In this randomized, single-blind, case-controlled, prospective study, the incidence and outcome of ceftriaxone-associated biliary pseudolithiasis in Chinese children was evaluated via ultrasonography. A total of 108 children diagnosed with hepatobiliary infection or pneumonia were randomized to receive ceftriaxone or ceftazidime. Serial gallbladder sonograms were obtained on days 1, 5 − 7 and 10 − 14 of therapy. Gallstones were detected in 43.10% of patients in the ceftriaxone-treated group and in 2.00% of the ceftazidime-treated group. The incidence of pseudolithiasis was significantly higher in the ceftriaxone-treated than the ceftazidime-treated group. Biliary precipitation abnormalities appeared after 2 − 7 days of treatment. After gallstones were found, the drug was stopped and symptoms resolved within 1 − 2 days. This study suggests that the risk of ceftriaxone-associated biliary pseudolithiasis should be considered when treating Chinese children.

Abstract
Gallstones are common with prevalences as high as 60% to 70% in American Indians and 10% to 15% in white adults of developed countries. Ethnic differences abound with a reduced frequency in black Americans and those from East Asia, while being rare in sub-Saharan Africa. Certain risk factors for gallstones are immutable: female gender, increasing age, and ethnicity/family (genetic traits). Others are modifiable: obesity, the metabolic syndrome, rapid weight loss, certain diseases (cirrhosis and Crohn disease), gallbladder stasis (from spinal cord injury or drugs, such as somatostatin), and lifestyle.

Abstract
There is much controversy about the treatment of Lyme disease with respect to 2 poorly defined entities: "chronic Lyme disease" and "posttreatment Lyme disease syndrome." In the absence of direct evidence that these conditions are the result of a persistent infection, some mistakenly advocate extended antibiotic therapy (>/=6 months), which can do great harm and has resulted in at least 1 death. The purpose of this brief report is to review what is known from clinical research about these conditions to assist both practicing physicians and lawmakers in making sound and safe decisions with respect to treatment.

Abstract
INTRODUCTION The objective of our study was to establish, through retrospective analysis of sonographic findings obtained by portable ultrasound devices, the frequency of pathological findings of the gallbladder and common bile duct in a randomized group of patients with infectious diseases. MATERIAL AND METHODS During five years (January 1, 2000 - December 31, 2004), gallbladder and common bile duct were examined by ultrasonography in 2691 adult patients (1440 males and 1251 females), mean age 48 +/- 17 years, ranging from 17 to 92 years at the Institute of Infectious and Tropical Diseases in Belgrade. The examination included the measurement of size and shape of the gallbladder, its wall and lumen, as well as measurement of caliber and content of the common bile duct. Conventional portable ultrasound devices, ALOKA SSD-500 and SSD-1000 (B-mod) with convex 3.5 and 5 MHz probes were used. RESULTS The cholecyst was normal in size (<120 x 50 mm) in 2164 (80.4%), and enlarged in 65 (2.4%) patients. The gallbladder was surgically removed in 163 (6.1%) patients, it was pseudoseptal in 141 (5.2%) and invisible in 44 (1.6%) patients. The gallbladder wall was normal in 2031 (75.5%), thickened in 259 (9.6%) and edematous in 173 (6.4%). Gallbladder calculosis was present in 310 (11.5%), and choledocholithiasis in 13 (0.5%) patients. CONCLUSION Development of morphological abnormalities of the gallbladder and common bile duct was frequent in non-selected patients with infectious diseases. The majority of them may be detected by portable ultrasound devices, which makes them rather applicable for large clinical-epidemiological studies.

Abstract
Ceftriaxone is a commonly used third-generation cephalosporin that has antimicrobial activity against many gram-positive and gram-negative organisms. Generally, ceftriaxone is a safe antibiotic; however, symptomatic biliary sludge has been reported in rare instances, most of which have involved children. It is uncommon for ceftriaxone to cause increases in laboratory indexes, such as bilirubin levels. We describe the case of a 53-year-old man who was treated with intravenous ceftriaxone 2 g every 12 hours. After 7 days of therapy, the patient's liver function test results, including total, direct, and indirect bilirubin levels, increased significantly from baseline, and the patient became jaundiced. A right upper quadrant ultrasound examination revealed biliary sludge and cholelithiasis without sonographic evidence of cholecystitis. Ceftriaxone was thought to be the responsible agent, and it was discontinued. The patient's jaundice subsided, and his liver function test results improved, returning to baseline within 14 days. Clinicians need to be aware of the association of ceftriaxone and biliary pseudolithiasis and hyperbilirubinemia, and monitor accordingly.

Abstract
Gallstone disease is common: >700,000 cholecystectomies and costs of approximately 6.5 billion dollars annually in the U.S. The burden of disease is epidemic in American Indians (60-70%); a corresponding decrease occurs in Hispanics of mixed Indian origin. Ten to fifteen per cent of white adults in developed countries harbour gallstones. Frequency is further reduced in Black Americans, East Asia and sub-Saharan Africa. In developed countries, cholesterol gallstones predominate; 15% are black pigment. East Asians develop brown pigment stones in bile ducts, associated with biliary infection or parasites, or in intrahepatic ducts (hepatolithiasis). Certain risk factors for gallstones are immutable: female gender, increasing age and ethnicity/family (genetic traits). Others are modifiable: obesity, the metabolic syndrome, rapid weight loss, certain diseases (cirrhosis, Crohn's disease) and gallbladder stasis (from spinal cord injury or drugs like somatostatin). The only established dietary risk is a high caloric intake. Protective factors include diets containing fibre, vegetable protein, nuts, calcium, vitamin C, coffee and alcohol, plus physical activity.

Abstract
Biliary pain is commonly reported in household surveys with the presumed cause being gallstones. When gallstones are absent or other abnormalities as a potential cause of similar pain do not exist, a different approach is necessary. Although trans-abdominal ultrasound can detect stones down to 3-5 mm, the advent of endoscopic ultrasound provides an even better definition for microlithiasis of < 3 mm. Duodenal aspiration of bile can further detect cholesterol microlithiasis or bilirubin granules, another potential source of biliary-type pain and perhaps even pancreatitis. Only in this way can acalculous gallbladder disease be clearly defined. The percentage of cholecystokinin-stimulated gallbladder emptying has been reputed to be the most sensitive diagnostic test for 'biliary dyskinesia', but abnormality of gallbladder emptying can be due to a smooth muscle defect of the gallbladder itself or heightened tone in the sphincter of Oddi. The value of surgical intervention has not been clearly established. The advent of laparoscopic cholecystectomy, however, has increased the number of patients with acalculous biliary disease who undergo surgery. Surgery is best done using impaired gallbladder emptying as the criterion for operation with improved outcome. Often, following cholecystectomy, biliary pain does not resolve the so-called 'post cholecystectomy syndrome'. Absence of the gallbladder as a pressure reservoir leaves the sphincter of Oddi as the prime determinant of bile duct pressure. Sphincter of Oddi dysfunction also exists in patients with an intact biliary tract and may become evident following cholecystectomy. Biliary manometry has clarified who might benefit from sphincterotomy. Choledochoscintigraphy is a non-invasive preliminary test. Advent of visceral hypersensitivity and better definition of this entity has shown, that in some of these patients with type III sphincter of Oddi, dysfunction appears to reside in duodenal hyperalgesia. It is clear that improved criteria are required to perform gallbladder emptying and better techniques to detect visceral hypersensitivity. Nonetheless, functional biliary pain in the absence of gallstone disease is a definite entity and a challenge for clinicians.

Abstract
Biliary sludge is a mixture of particulate matter which has precipitated from bile. It generally consists of cholesterol monohydrate crystals, calcium bilirubinate or other calcium salts. In a clinical setting, biliary sludge is almost always an ultrasonographic diagnosis. Although it is less clinically applicable, direct microscopic examination of gallbladder bile is far more sensitive than ultrasonography into sludge detection, and has to be regarded as the diagnostic gold standard. The overall prevalence of sludge in the general population is relatively low. However, several clinical conditions are associated with a particularly high prevalence of biliary sludge, including pregnancy, rapid weight loss, total parenteral nutrition, octreotide therapy, bone marrow or solid organ transplantation. The clinical course of biliary sludge varies, and complete resolution, a waxing and waning course, and progression to gallstones are all possible outcomes. It may cause complications usually associated with gallstones, such as biliary colic, acute cholecystitis, and acute pancreatitis. The main pathogenic mechanism involved in sludge formation is probably gallbladder dismotility, and in selected patients measures aimed to maintain adequate gallbladder contractions has been shown to effectively prevent sludge development.

Abstract
Acute biliary pain represents the main symptom of gallbladder stones, less frequently of common bile duct stones or functional disorders of the biliary tract. The pain lasts at least 15 minutes, is typically localized to the epigastrium or the right upper quadrant of the abdomen and my radiate to the right shoulder. Diagnosis of biliary pain is primarily based on clinical criteria, ultrasound allows detection of causative gallstones with high sensitivity and specificity. Analgesics and laparoscopic cholecystectomy are widely accepted as standard therapy for the majority of patients.
